Patent EP-0361660-A2 (EP)
Inventor: BARKER VICTOR GRAHAM
IPC: B21D31/04
Filed: 1989-08-10
Abstract: A method of making a sheet metal article comprises the steps of forming a workpiece of lesser area than that of the article, slitting an area of the workpiece corresponding to a non-functional zone of the article to render the non-functional zone extendable, shaping the remainder of the workpiece as needed, and extending the non-functional zone to produce the article. By reducing the size of that part of the workpiece corresponding to the non-functional zone of the finished article, materials are saved in the manufacture of the article. 
     The slitting may be such as to define a plurality of interconnected tongues (11) extending in the longitudinal direction of the non-functional zone, or a plurality of interconnected strips extending in the transverse direction. Thus, the extending of the non-functional zone may be in either the longitudinal or the transverse direction. 
     The invention also extends to articles made by the method of the invention.

Abstract: Up until now, the greater the frequency hop permitted at the input to the phase discriminator, the greater the period for evaluating the control capability of a phase-locked loop has been. The novel method provides the possibility for evaluating the control capability of the phase-locked loop even where large frequency hops are permitted. The change in phase difference caused by a frequency hop is detected by means of a gradient threshold so that even when the absolute phase difference caused by this exceeds the value of the alarm threshold, this no longer leads to a synchronisation alarm being triggered. The alarm threshold can therefore be located quite low and the control capability of the phase-locked loop can be evaluated within a short time. <IMAGE>

Abstract: A coefficient setting circuit (65) sets in registers (66 and 67) coefficients corresponding to position of each of magnetic heads (56a, 56b, 57a, 57b) on a rotary drum (58). A counter circuit (61) counts the number of pulses of a reference clock signal (CK1) to be employed as a reference for a rotation control of rotary drum (58). Comparison circuits (63 and 64) compare the coefficients set in registers (66 and 67) with a count value of counter circuit (61) to output reset pulses (r1 and r2) when detecting a match between the set coefficients and the count value. In response to these reset pulses (r1 and r2), counter circuits (69 and 70) are reset to start counting operation of a reference clock signal (CK2). Consequently, decoders (73 and 74) output timing pulses for controlling timing of recording or reproducing operation of each magnetic head. The coefficients to be set by coefficient setting circuit (65) are altered in accordance with alterations in position of each magnetic head and in shape of the rotary drum, resulting in constantly appropriate timing pulses.

Abstract: In an X-ray imaging system, images of a moving bolus of contrast medium are acquired by the emission of X-ray radiation pulses through an object to be imaged while controlling the longitudinal movement of an X-ray imaging device of said system in a continuously sweeping manner over said object. For limiting motion induced blur in the acquired images to an acceptable level, X-ray exposure values are developed which limit the duration of the X-ray pulses so that they do not exceed a predetermined maximum duration. In a preferred embodiment multiple passes of the imaging device are made over the object.

IPC: G06F12/08

Abstract: A translation of a portion of a virtual page number to a portion of a physical page number in a "TLB slice." The slice translation is used to index into a physical cache memory which has virtual tags in addition to physical tags and whose addresses are physical. By comparing the virtual tag to the input virtual address page number, it can be determined whether there was a hit or a miss in the combination of the TLB slice and the cache memory. By translating only a few bits of the virtual address to a few bits of a physical address, the speed of the device is greatly enhanced. This increased speed is achieved by making the TLB slice direct-mapped and by taking advantage of its small size to build it with special hardware (either high-speed RAM (random access memory) or with latches and multiplexers). There is no separate comparison at the TLB slice output for determining a TLB slice hit. The subsequent cache tag comparison is used to indicate both whether the translation was correct and whether there was a cache hit. To achieve this dual purpose comparison, however, a virtual tag must be combined with a physical cache to determine whether there is a hit, since the entire virtual address has not been translated and therefore there is no translated physical address to compare with a physical tag.

Abstract: The device comprises on the one hand an elongate scale (7) consisting of a succession of magnetic north poles and south poles, and on the other hand a measuring head (9) with at least a first and a second magnetic field sensor (21, 23) which are subjected to the effect of a magnetic field which alternates as a function of time due to the alternating passage of north poles and south poles during a displacement (15) of the scale in its longitudinal direction with respect to the measuring head. The two magnetic field sensors (21, 23) are arranged so that they are always situated opposite one and the same point on the scale (7), the first sensor (21) being sensitive to variations in the magnetic field component extending parallel to the longitudinal direction of the scale (7), the second sensor (23) being sensitive to variations in the component extending parallel to the connecting line (19) between the scale (7) and the measuring head (9). Because the points where the direction of these magnetic field components is reversed correspond to different points on the scale (7), the output signals of the two sensors (21, 23) are phase-shifted with respect to one another, so that the direction of the displacement can be readily determined.

Abstract: Automatic particle pattern judging method, in which particles to be tested, such as blood cell particles, are delivered into not only a reaction vessel but also a reference vessel (12), and an amount of the particles delivered into the reference vessel is measured and a judgement whether the particle pattern formed in the reaction vessel is agglutinated or not is conducted by correcting values of a reaction liquid contained in the reaction vessel concerning parameters for the judgement or correcting threshold values, with which the values of the test liquid concerning the parameters should be compared in accordance with the amount of the particles delivered into the reference vessel. Therefore, by the method according to the invention, even when the amount of particles to be tested delivered into the reaction vessel is varied for some reason, it is possible to judge correctly whether the particle pattern is agglutinated or not.

Abstract: A motor controller includes a set of thyristors which couple the motor to a source of alternating electricity. A detector senses when the voltage of the source makes a zero crossing. A mechanism is provided to vary the frequency of a clock signal (GATE CLOCK) at a rate determined by a user selectable input which represents the rate at which the motor speed is to change during starting or stopping. The clock signal (GATE CLOCK) is applied to a counter (71) which produces an active trigger signal (FIRE) when a given number of clock signal cycles have been counted following a zero crossing of the source voltage. The active trigger signal causes a trigger pulse circuit (72) to apply a brief trigger pulse to gate electrodes (21, 22, 23) of the thyristors. The varying frequency of the clock signal (GATE CLOCK) alters the relative times at which the thyristors are triggered to vary the amount of voltage applied to the motor. Different frequency variation functions can be stored in a memory for the starting and stopping modes.

Abstract: An integrated hardware generator (12) for generating digital signals representative of vectors, polygons and conics primitives and area fills therefore is disclosed. The primitive signals are used in the formation of a final digital output signal read into a bit map memory of a graphics display processor. Its operation is based on applying one or more of a set of internal subfunctions to generate mathematical solutions for rendering each geometric shape as a graphics primitive digital signal. The basic building block of the generator (12) is a digital differential analyzer (60) which is adapted to accumulate fractional (subpixel) components of x/y coordinate data and to signal when the accumulation overflows across pixel boundaries. This occurrence enables an increment or decrement of the x/y coordinates that indicate the pixel addres to be loaded (drawn). The digital differential analyzer (60) forms an independent vector generator and comprises a pair of input differential comparators (62), an arithmetic logic unit (64) and register and counter files (66a, 66b). On receipt of a command from a host processor the comparators (62) receive updated x and y data, compare them to the present values which are stored in the register file (66) and forward the differences to the arithmetic logic unit (64). When either the x or y value exceeds the pixel boundary, the arithmetic logic unit (64) computes the coordinates of the next pixel to be filled and inserts them into the register file (66) to replace the previous values.
